The only two reasons to rush the Russia investigation are ignorance or politics

Those calling for a speedy conclusion to the congressional investigations into Russian election meddling are either doing so for strictly political reasons, or they have no idea how long investigations take and what is required to do them well.

Recent indictments filed by Special Counsel Robert Mueller in the Russia probe (and the prospect of others) should have already demonstrated to congressional investigators pursuing similar lines of inquiry that there were crimes committed, that there was a cover up and that much likely remains to be done to reveal the full extent of wrongdoing.
